参考答案:
46.正确答案:B
答案解析:此题考查被动语态的进行式:be +being +PP.(过去分词)。
47.正确答案:D
答案解析:本句主语是this page,与check是被动的关系。need to be checked:需要被核实。
48.正确答案:B
答案解析:因为serve是及物动词,其动作承受者tea作主语,表示经常发生的情况,故用一般现在时的被动语态。
49.正确答案:A
答案解析:本句的意思是:“我要是记得把窗子关起来的话,小偷就进不来了。”remember后接动名词表示记得过去曾做过某事,接不定式则表示记得要做某事。本句说的是:“记得把窗子关起来”。因此A)to close是答案。注意remember后面不能用动词不定式的完成式。至于选项B) closing,因为这里“关窗子”这件事“我”并没有做,所以是不对的。
50.正确答案:C
答案解析:在本句中,send 为短暂性动词,不能用进行时态。所以B和D两项错误。A和C的区别在于不定式的时态,句首表示时间概念的ancient表明不定式动作在句子谓语动作之前,不定式要用完成式, 因而答案是C.
